Abstract

467,788. Toys. HORN, E. Nov. 9, 1936, No. 30536. Convention date, Feb. 7. [Class 132 (iii)] A closed track for motor toys not having flanged wheels is provided with two adjacent concave trackways 1, connected by a middle strip and electrically connected by a conducting bridge 8, each trackway having a separate contact rail 10 connected by the insulated conducting bridge 9 to independently regulable slides 14 moving over contacts 12 connected with coil tappings in the current supply transformer 11 so that the toys can be caused to travel simultaneously on both trackways in the same or opposite directions at different and variable speeds. Voltages of about 14 to 20 volts can be supplied to the track. The track is assembled from different sections, one section 7, Fig. 2, carrying the bridges 8 and 9. Branch trackways 1<1> pass under or over bridges 6 and connect one trackway 1 with the other by means of built-in switch points 2 having oscillatable tongues 4, which may be operated by electromagnets 3 and armatures 3<1>. At the points 2 the contact rails are interrupted and electrically connected by an underneath bridgeplate b, Fig. 5. Circuit interruptions 5 are provided in the branch trackways 1<1> for ensuring that the circuits under different voltages for the two main trackways 1 are not connected together. The toys are provided with a contact tongue S, Fig. 6, which slides on the contact rail 10 and acts as a current collector for a motor built into the toy. The contact rails 10 are insulated by lug-fixed plates of insulating material on the underside of the trackways as shown in Figs. 4 and 5.
